Black Fox, Timmins – Enhanced Growth Strategy
Our growth strategy in the Timmins region, which started in April 2017 with the acquisition of Lexam VG Gold, reached a
second important milestone on October 6, 2017 with the purchase of the Black Fox Complex. Black Fox consists of:
1) the fully operational Black Fox underground gold mine, 2) the Black Fox-Stock mill, 3) an experienced workforce,
and 4) the nearby Grey Fox and Froome development projects. The addition of Black Fox boosts our global 2018
production guidance to between 172,000-185,000 gold equivalent ounces.
Gold Bar Project, Nevada – Major Permitting Milestone
The Gold Bar Project has achieved a major milestone in the permitting process with the publication by the Environmental
Protection Agency (EPA) of the Notice of Availability of the Final Environmental Impact Statement (EIS) in the Federal
Register. Following a regulated review period, a signed Record of Decision will be published, signifying the completion of
the National Environmental Policy Act (NEPA) process. The Record of Decision is expected in early November this year
and development of Gold Bar is planned to begin upon receipt, in line with our earlier estimates. Gold Bar is expected to
contribute an average of 65,000 ounces to our annual gold production beginning in 2019.
Los Azules, Argentina – Robust Economics in New PEA
The results of the 2017 PEA demonstrate that Los Azules could become a robust, high margin, rapid pay-back, and
long-life open pit mine at current copper, gold and silver prices. Financial highlights from the 2017 PEA, assuming a
$3.00 per pound copper price, are: 1) $2.2 billion after-tax net present value (NPV@8%), 2) an internal rate of
return (IRR) of 20.1%, and 3) a payback period of 3.6 years and a total mine-life of 36 years. Estimated average
annual copper production is 415 million lbs. at a cash cost of $1.11/lb. during the first 10 years of mining
operations. The PEA report is available for review on our website (www.mcewenmining.com/operations/los-azulesexploration)
and SEDAR (www.sedar.com).
San José Mine, Argentina (49%(2)) – Improving Production
Our attributable production from San José in Q3 was 11,862 gold ounces and 747,960 silver ounces, for a total of 21,834
gold equivalent ounces. Year-to-date our attributable production was 64,563 gold equivalent ounces, 2.8% below the same period in 2016.

El Gallo Mine, Mexico – Overcoming Challenges
Production in Q3 was 7,213 gold equivalent ounces, compared to 11,849 gold equivalent ounces during the same period
in 2016. Production in Q3 continued to be below our expectations as a result of a serious mechanical failure at the end of
July that removed the crushing circuit from operation. As a result we were unable to crush and place fresh ore to leach on
the leach pad for a period of time. We currently have almost twice our normal crushing capacity available for the
remainder of the year. Production is improving on account of the increased throughput, and access to better grades of ore
in the pit that was predicted in the second half of the year. Increased production in Q4 will partially compensate for the
shortfall experienced to date.
Financing
In order to purchase Black Fox and provide funding for further investment in capital spending and exploration, we
completed a financing in which a total of 20,700,000 shares and 10,350,000 warrants were sold at a price of $2.25 per
share and associated one-half warrant, for aggregate gross proceeds of $46,575,000. Each whole warrant entitles the
holder to purchase one share at an exercise price of $2.70 per share until September 28, 2018.
Financial Results
Operating costs for the quarter ended September 30, 2017 will be released with our 10-Q Quarterly Financial Statements
in early November. As of October 12, 2017 we are debt-free with liquid assets of approximately $60 million.
